Final answer:
The claim that a cell can reorganize its actin cytoskeleton for various functions including cell locomotion, shape changes, phagocytosis, and cytokinesis is true. Actin microfilaments are dynamic and facilitate these processes in the cell.
Step-by-step explanation:
The statement that a cell can reorganize its actin cytoskeleton, which is required for cell locomotion, changes in cell shape, phagocytosis, and cytokinesis, is true. Actin microfilaments contribute to the cell's structural integrity but are also dynamic, allowing cells to adjust their shapes and move.
They are key components in various processes, such as enabling white blood cells to move to infection sites and engulf pathogens, helping in the formation of cleavage furrows during cell division, and allowing cell motility through extensions called pseudopodia. The actin filaments can rapidly polymerize and depolymerize in response to cellular signals, which is essential for the aforementioned cellular activities.
